Dependencies

Setup

  • Set path to OpenCL SDK:
    • For Intel OpenCL set export INTELOCLSDKROOT=<path to intel ocl sdk>, e.g., export INTELOCLSDKROOT=/usr/local/intel/opencl
    • For NVIDIA OpenCL set export CUDA_PATH=<path to cuda home>, e.g., export CUDA_PATH=/usr/local/cuda
    • For AMD OpenCL set export AMDAPPSDKROOD=<path to amd ocl sdk>, e.g., export AMDAPPSDKROOD=/usr/local/amd/opencl
  • Set MATLAB_ROOT environment variable, e.g., export MATLAB_ROOT=/usr/local/MATLAB/R2017a
  • mkdir build
  • cd build
  • cmake ..
  • make
  • make install

Log

  • Version 0.1, 2017-07-20

    Includes feature embedding code/models, 4-D cost volume construction and processing, and forward-backward consistency checking. Part of poster-processing (EpicFlow inpainting, homography fitting) can not be included due to license issues. We expect to release them in future versions. You may download the EpicFlow code (or other inpainting code), and replace the match file with our output to obtain a dense optical flow filed.
